Cleaning wet sheet

摘要

A wet cleaning sheet 1 comprises an aqueous liquid-retaining layer 4 having an aqueous liquid-containing polymer and a chemical-containing layer 2 or 9 containing a chemical which causes the polymer to release the aqueous liquid. The aqueous liquid-retaining layer 4 and the chemical-containing layer 2 or 9 are formed and/or arranged in such a manner that they are kept out of substantial contact under no load applied but brought into contact with each other with a prescribed load applied whereby the aqueous liquid is gradually released from the polymer by the action of the chemical.
